The core advantage is automation and precision. While spring-type crushers require manual adjustment and can have uneven pressure, the hydraulic system provides constant, measurable pressure. It allows for one-button adjustment of the discharge size and offers superior protection; if an unbreakable object (like iron) enters, the hydraulic cylinders retract instantly to prevent roller damage and then reset automatically.

Our “Long-Life” roller skins are made from a proprietary high-manganese cast alloy. For abrasive materials like granite or river pebbles, the service life typically ranges from 8,000 to 12,000 hours (roughly 1–3 years depending on usage). The hydraulic system also ensures even wear across the surface, extending the lifespan by up to 30% compared to traditional models.

Yes, absolutely. By precisely controlling the hydraulic gap (the distance between the two rollers), you can adjust the output size from 0-3mm, 0-5mm, to 0-10mm. This allows you to meet strict industry standards for high-quality concrete sand with an excellent cubic shape and low needle-like content.

Not at all. We’ve designed the HSM hydraulic unit for “Simplified Maintenance.” The system is modular and self-contained. Most daily checks involve just monitoring the pressure gauge and oil levels. Furthermore, our PLC control system provides automated early warnings, allowing you to address issues before they lead to downtime.

The maximum feed size depends on the roller diameter. For our standard hydraulic models, it ranges from 30mm up to 60mm. To ensure the highest efficiency and lowest wear, we recommend a consistent feed size. If your raw material is larger, we can provide a complete solution including a primary jaw crusher.
